(a) The efficiency of one graded-layer In0.3Ga0.7 N pin solar cells with four different graded energy bandgap of 3.01, 2.81, 2.63, and 2.46 eV as a function of the graded layer thickness. (b) The energy band diagram of one graded-layer In0.3Ga0.7 N pin solar cells with four different graded energy bandgap of 3.01, 2.81, 2.63, and 2.46 eV.
